Ronald and Peter Goldstein

The brothers and their family held about 20m Kingfisher shares after selling Superdrug to the retail giant in 1987. We assume they have sold them and will not have been hit by the collapse of Woolworths, which had been part of Kingfisher. Selling the shares will have netted at least £70m. Ronald, 72, and Peter, 69, who are based in Kingston upon Thames, have several small property firms.
